Chondrocalcinosis of the Knee with Gout and Rheumatoid Arthritis

X-RAY demonstration of multiple articular chondrocalcinosis has been advanced as a useful preliminary diagnostic sign for pseudogout, a disease marked by deposition of calcium pyrophosphate dihydrate (CPPD) crystals.1 When present, chondrocalcinosis is usually most evident in the knee joint, where in turn the menisci usually are most obviously involved.A recent uncontrolled study by Dodds and Steinbach2 reported meniscal calcification in 10 of 31 patients with gout, 6 of whom had involvement of all 4 menisci.
